Previewing the current offerings, the PlayStation blog explained: "'Killing Floor 2' is a first-person co-op zombie shooter set in the immediate aftermath of 'Killing Floor'.

Meanwhile, the computing giant also encouraged gamers to try their hand at the critically-acclaimed 'Life is Strange'.

The blog read: "From there, rewind a bit with the excellent 5-part episodic adventure 'Life is Strange'. Follow the story of Max Caulfield, a photography senior who discovers she can rewind time. Here's the catch: changing the past can greatly impact the future. See for yourself why this one racked up critical acclaim and numerous awards. (sic)"

In addition to revealing the free PlayStation Plus games, the technology firm has also announced discounts to the 'WWE 2K17' and 'NBA 2K17', and 'The Division' and 'Rainbow Six Siege' bundles.
